Author Dusty Phillips Reviewers

Who this book is for
This book specifically targets people who are new to object-oriented programming. 
It assumes you have basic Python skills. You'll learn object-oriented principles in 
depth. It is particularly useful for system administrator types who have used
Python as a "glue" language and would like to improve their programming skills.
If you are familiar with object-oriented programming in other languages, then this 
book will help you understand the idiomatic ways to apply your knowledge in the 
Python ecosystem.
Conventions
This book uses a variety of text styles to distinguish between different kinds
of information. Here are some examples of these styles, and an explanation of
their meaning.
Code words in text, database table names, folder names, filenames, file extensions, 
pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We 
look up the class in the dictionary and store it in a variable named 
PropertyClass
."
A block of code is set as follows:
def add_property(self):
property_type = get_valid_input(
"What type of property? ",
("house", "apartment")).lower()
payment_type = get_valid_input(
"What payment type? ",
("purchase", "rental")).lower()
When we wish to draw your attention to a particular part of a code block, the 
relevant lines or items are set in bold:
def add_property(self):
property_type = get_valid_input(
"What type of property? ",
("house", "apartment")).lower()
payment_type = get_valid_input(
"What payment type? ",
("purchase", "rental")).lower()
